HOSE-STRIPPING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 640,091, dated December 2K6, 1899.

Application filed December 30, 1898. Serial No. 700,698. (No model.)

The object of my invention is to produce a' machine for stripping the-metallic terminals from hose.

In-air-brake and steam-heatin g systems for railway-oars the exible connections ordinarily consist of'sections of rubber hose provided with terminal iittings by which the `hose-sections. may be connected to the pipes of a' caror cars of a train. Heretofore when it was desired for any reason to separate the terminals from the hose it has been necessary to chip away the rubber hose, thereby injuring or destroying the hose. Such a method is, moreover, tedious and expensive. My in- .vention provides means for quickly stripping the'hose Without injuring it.

My apparatus consists, essentially, of a coacting vise and tension-creating mechanism or stripper, and in its preferred form of embodiment those members are designed to be actuated by air or other iiuid pressure.

In the accompanying drawings, Figure I is a side elevation, partly in section, of my apparatus complete, sh owing the vise and stripper in the inoperative position, a hose being illustrated in position ready to be stripped. Fig. II illust-raies a portion of the apparatus, showing the vise and stripper in the positions which they respectively occupy after a complete operation.

Referring to the figures on the drawings, 1 indicates a bench or table, and 2 aiXed support above the same-aa for example, the ceiling of the roomin which the table is lo'- cated. Coperating with the table I employ a vise 3 and a stripper 4. The vise consists, preferably, of uprights 5 and 6, rigidly secured between the bench 1 and the ceiling 2. Between the uprights worksaclamping member 7. The vise being preferably operated by Huid-pressure, the member 7 is affixed to the lower end of a piston-rod 8, that is attached to a piston 9, Working within a cylinder 10, secured to the uprights 5 and 6. The

piston is yieldingly urged to its upward limit of movement, as by a coiled spring 11, sur'- rounding the rod 8, seated at one end against the piston 9 and at the other end against the cylinder-head 12.

The stripper consists,essentially,of tension'- creating mechanism, and in its preferred form of embodiment comprehends a pair of journalsupports 13, withinwhich is revolubly mounted the shaft 14 of'a sprocket-pinion 15, and journal-supports 16,within which is revolubly mounted the shaft17 of a sprocket-Wheel 18. Around the pinions 15 and 1S passes an endless sprocket-chain 19, one link of which carries a hook or engaging member-19 and any l ient and simple mechanism for impartinglimited reciprocal movement to the hook. It would, for example, be practicable to join the hook 192L directly to the piston 21, the piston 21 being intended to represent suitable hookactuating mechanism and illustrating the preferred fluid-actuated mechanism comprehended by the preferred form of embodiment of my invention.

As Was specified above, the vise and stripper are preferably iuidpressure -actuated mechanisms, and therefore in illustrating the preferred form of embodiment of my invention I show a iiuid-pressure-supply pipe 26, communicating with a source of uuid-pressure supply-as,for eXample,a compressed-air reservoir 27 at one end-and through branch pipes 28 and 29 with the interior of the cylinders 10 and 23, respectively. The pipe 26 is preferably provided with a depending loop 30, that carries near its bend, within easy access of an Operator, a valve-shell 3l, Within'which worksa three-way valve (not illustrated) that is adapted to loe manipulated as by a handle 32. By turning the handle 32 in one direction air-pressure is allowed to pass from the pipe IOO ' 26 through its loop 30 to the branch pipes 2S and 29. Turned in another direction the valve connes the air-pressure Within the pipe 26 and allows exhaust from the branches 28 and 29 through the discharge-port 34. The branch 29 is preferably provided with an exhaustpipe 35, controllable as by a cock 36.

37 indicates a cock intersecting the pipe 29.

38 indicates a section of hose, such as is provided with metallic terminals, which my apparatus is designed to strip from it. These terminals usually consist of rings or fittings provided with male or female screw-threads.

39 indicates a connecting-eyelet adapted4 to be screwed upon a male thread, and 49 an eyelet adapted to be screwed into a female thread. The eyelets may be of any suitable shape adapted to make a firm union With the metallic terminal to which they are respectively fitted.

In operation a Workman attaches to a section of hose to be stripped an eyelet or eyelets at its opposite ends and engaging the hook 19" with one of the eyelets lays the hosesection upon the table l, under the clamping member`7. The clamping member is then depressed, so as to grip the hose-section, after the manner illustrated in Fig. II. The stripper is next actuated to create a tension upon the hook 19, which being connected with an eyeletfor example, the eyelet 49-extracts the terminal to which the eyelet is secured. In practice the terminals are secured by metallic bands or clips, which are of course first removed before stripping the hose. The operation of the vise and of the stripper may be controlled by manipulation of the valve-handle 32, its movement'in one direction serving,

through application of pressure behind the pistons 9 and 22, respectively, to drive the clamping member 7 against the hose-section and to create tension upon the hook 19a. After the terminal is withdrawn the turning of the handle 32 permits exhaust of air through the port 34 and the repulsion of the pistons 9 and 22 under the force of their respective springs. The cock 36 is provided as a means of expediting the exhaust when required. After the stripping of one terminal the hook 19a is disengaged. from the eyelet to which that terminal is secured, the hose-section is reversed, the hook is engaged with the other eyelet, and the operation is repeated. The cock 37 is provided in order to permit the operation of the piston 9 independent of the piston 22, so that the vise, if desired, may be used independently of the stripper.

What I claim is l. In hose-stripping apparatus, the comblnation With a vise, of a pair of sprocket-gears, an endless chain carried thereon, a hook upon the chain, and means for actuating the chain upon the gears in order to produce movement of the hook, substantially as set forth.

2. A hose-stripper consisting of a pair of suitably-mounted sprocket-gears, an endless chain thereon, a cylinder, a piston within the cylinder connected with the chain, and an engaging member carried by the chain, substantially as set forth.

In testimony of all which I have hereunto subscribed my name. Y
